摘要
根据矿用防爆胶轮车井下巷道作业时恶劣工作环境的特点,在ADAMS软件中建立胶轮车的多体动力学模型,并针对左右颠簸路面进行动态仿真分析,获得随机激励下的峰值力。在ANSYS软件中建立车体的有限元模型,用有限元法对车架进行动态应力分析,得到了各部位的应力分布情况。通过分析可知,最大应力为305 MPa,满足强度要求。其中机架与销轴铰接板的连接处、上下销轴的表面都出现了应力集中的现象,其他位置受力较小,可以对车架的结构进行优化改进。
According to the the bad working vehicle underground tunnel job characteristics, dynamics model in the ADAMS software,and conditions of the mine explosion-proof rubber-tyred established rubber-tyred vehicle bodywork multi-body dynamic simulation analysis on left and right bumpy pavement,dynamic stress analysis on the main frame after getting the random excitation peaks. Establishment of finite element body model in ANSYS software. Dynamic stress analysis using the finite element method frame, get the stress distribution of each part. Through the analysis, the maximum locations smaller force,it could optimize the improvement of the structure of the frame.
